Be it known that 1, EDWARD J. Denman, of Uneida. in the county of Madison, in the State of New York, have invented new and useful Improvements in a Combined Safety-Razor and H air-Cutter, of which the followin r, taken in connection with the accompanyingI drawings, is a full, clear. and exact description.

This invention relates to improvements in combined safety-razors and hair-cutters, in which a suitable supporting-frame is provided with ways for the reception of an adjustable comb and a razor-blade, which latter is held between the comb and frame, and "the frame is adapted to receive a suitable handle at either end. while ythe comb is provided with means for receiving the same handle and sup-- porting it at substantially right angles to the comb and blade.

Une of the objects of this invention therefore is to enable the handle to be used at either end or at the comb side of the frame, so that the razor or comb side may be used alternately with either the right or left hand, or when the handle is attached to the comb side the cutting edge is always presented to the face and in this position may be used either for shaving or trimming the hair or beard.

A further object is to provide the comb guard with suitable notches or marks which are adapted to be registered with the edge of the razor-blade to indicate the correct rela ti ve position of the comb and blade for use in shaving.

A still further object is to interpose a thin guard plate between the comb and' razorblade near their working edges to prevent contact of the teeth of the comb-guard with the cutting' edge of the razor-blade, thereby preventing picking or dulling said cutting edge.

Another object is to convex one side of the frame to lit the adjacent concave face of the razor and to make the raZor-blade-receiving pocket shallow enough to allow the guard plate to impinge the razor-blade against said convex face when the guard-plate is clamped in position, so that the razor-blade is held solely by the clamping of the guard-plate.

'.lhe broad object of the invention, however, is to provide a combined safety-razor and hair-planer capable of being used in the right or left hand and in which either the comb or razor side may be applied to the face or hair.

Other objects and uses will appear in the following' description.

ln the drawings, Figure 1 is a perspective view of a combined safety-razor and hair planer or trimmer, showing the handle in full at one end and in dotted lines as applied to the comb side of the device. Figs. 2, 3, and d are sectional views taken, respectively, on lines 2 2 and 3 3, Fig. 1, and 4 d, Fig. 2. Fig. 5 is a perspective view of thedetached comb and guard-section. Fig. 6 is a perspective view of the detached supportingframe. Fig. 7 is a perspective view of the razor-blade. Fig. S is a perspective view of a portion of the handle.

In carrying out the objects stated ,l provide a suitable substantially rectangular frame consistingof a top bar 1, end pieces 2, and transverse bars 3' and 4f, all of which parts are formed of metal, the metal bar 1 and transverse bars 3 and 4 being' united at their ends to the end pieces 2 to form a rigid integral structure adapted to receive a comb 5 and .razor-blade 6. The top piece 1 is formed with a central threaded aperture 7 for receiving a clamping-screw 8, which is adapted to be passed through an elongated slot 9 in the combsection 5 for permitting the adjustment of said comb-section and clamping it in its adjusted position. The end pieces 2. are each provided with a threaded aperture 8 for receiving the threaded end 9 of a suitable handle 10, and it is therefore apparent that this handle may be screwed or secured in either of the apertures 8 to be used in connection with either end of the frame for right or left hand shaving or hair-trimming. These end walls 2 are also provided with lateral slots or ways 1l, in which the opposite ends of the comb-guard 5 are slidingly mounted and held in operative position while being adjusted between the main fraaie and suitable flanges 12 for :forming the outer walls of the grooves l1. The whole frame is comparatively thin transversely of the blade and comb-section, so that either the comb or blade side of the device may be used for trimming the hair or shaving, as may be desired.

The lengthwise bar 3 is depressed to one side of the plane of the grooves 11 and its face is preferably convex transverselyj as best seen in Fig. 2, to conform to the concave face of the razor-blade, which it is adapted to engage and against which the razor-blade is seated.

'if he bar et connects the lower ends of the end pieces 2 and is separated from the lower edge of the bar 3 to form an intervening' slot or space 13, through which the razor-blade may be inserted, with one of its concave faces resting upon the convex faces of the bar 3, the space 13 being equal to or slightly greater than the thickness ot' the back of the razorblade in order that the latter may be readily inserted from the lower side upwardly through the opening 13. The opposite edges of this bar 1 are substantially parallel with the lower edge of the bar 3 and are therefore parallel with each other, and the inner face of the bar 4 is disposed in a plane coincident with one side of the slots 11, so as to form a bearing for the free ends otl the comb-teeth fromend to end of the frame when said comb is placed in its guides 11.

The guard-plate or comb 5 is adjustable in the guides 11 and is provided with a series of comb-teeth 14 and with comparatively shallow notches 15, extending' inwardly from its lower edge at opposite ends of the portion of the guard-plate in which the comb-teeth are formed, the depth of these notches 15 being uniform and serving to determine the amount of the projection ot' the teeth 1a beyond the cutting edge of the razorvblade in the manner presently described. This guard-plate 5 is also made ot' comparatively7 thin sheet metal and provided with a central boss 16 and a suitable linger-piece 17, the boss 16 being provided with a threaded aperture 1S, similar to the apertures 8/ for receiving the threaded end ot the handle 10, while the finger-piece 17 serves as a means for effecting the adjustment of the blade 5 along its ways 11 in its supportingframe 1.

The blade 6 is of the ordinary type used in safety-razors, and when seated in its recess in its supporting-frame one of its concave faces rests upon and against the convex face of the bar 3,with the hack of the blade resting against the lower face of the lengthwise upper bar 1, while the cutting edge extends through the slot 1 13 and its opposite cu tting-face engages and lies in close proximity to the bar 4:,so that the razorblade is practically interposed between the bars 3 and l and also between the bar 3 and guard-plate 5. The cutting edge of the razorblade extends a slight distance beyond the lower edge of the bar 4. This bar 11 is quite thin and serves as a separator between the cutting edge ot' the razor-blade and lower part of the guide or comb-plate 5 to prevent contact of the teeth ot' the guard-plate with the cutting edge of thc razor-blade, and at the same time enabling these parts to be brought to gether.

It is now obvious that my invention comprises, essentially, a supporting-frame, razorblade, and guard-plate or comb with means position, and a suitable handle which is adapted to be secured to either end of the frame or to the side of the guard-plate.

In assembling the parts of my invention the razor-blade is inserted back foremost and 'from the under side through the slot 13 until its back edge comes in contact with the lower face of the bar 1 and one of the concave sides ot' the bladeresting against the convex face of the bar 3. This brings the lower portion of the razor-blade closely against the bar 4;, with its cutting edge projecting slightly beyond said bar. The guard-plate 5 is next placed in operative position, with its opposite ends seated in the ways 11, and this blade is adjusted until the upper edges of the notches 15 are registered with the cutting edge ot' the razor-blade 6, in which position the slot 9 is registered with the aperture 7, and the clamping-screw 8 is then inserted through the slot 9 and engaged with the threaded aperture 7 until the head of the clamping member 8 is im pinged against the adjacent face of the plate 5. lt is now apparent that this plate 5 is held in the ways 11, and by tightening the screw 8 said plate is lirmly impinged against the protruding portion of the back of the razor-blade and forces said receptacle firmly against the convex seat ot' the bar 3.

lt will be observed upon reference to Fig. 2 that when the guard-plate 5 and razor-blade are clamped in a manner just described the distance between the upper portion of the bar 3 and adjacent face of the plate 5 is considerably greater than the distance between the lower portion of the bar 3 and adjacent blade of the plate 5 and that the lower portion of the blade 6 bears against the side of the bar 4 opposite to that engaged by the guard-plateV 5, and therefore the razor-blade is firmly held against edgewise movement, and, in fact, the mere act of clamping the blade 5 against the adjacent face of the razorblade tends to force the back of said razorblade against the lower edge of the bar 1, thus lirmly holding the blade against accidental movement while in this position.

Tn operating my invention as a safety-razor the guard-plate is adjusted so as to bring' the upper edges of the notches l5 into exact registration with the cutting edge of the razorblade, whereupon the clamping-screw 8 is tightened to hold the guard-plate in its adjusted position. The handle 10 may then be screwed into the aperture 18, so as to project from the comb side ot' the supporting-frame, which brings the razorblade at the opposite side ready for use in shaving, although it is clearly evident that by tilting' the whole device at a greater angle than is necessary for shaving the comb edge may be drawn through the hair or beard to cause the razor edge to for holding the guard-plate in its adjusted l trim the hair or beard to the desired length,
